DEVICE FOR EDGING LAWNS.

Application filed May 21,

One form of the invention is shown in the accompanying drawing, in which Fig. l is a plan view of the lawn edger, Fig. 2 an elevation showing the ratchet arm in its lower posi- 5 tion, Fig. 3 an elevation showing the edger in place on the edge of a walk with the ratchet arm raised ready to begin its movement, and Fig. 4 an end elevation in which the pawl is omitted.

The circular cutter (1) has attached to it the ratchet wheel (2) and is mounted on the hardwood hub or roller which is 'free to rotate on the pin or spindle (4) mounted in the frame (5) and footboard The 15 back end of the footboard (6) is provided with a slider or heel piece (7). On the same spindle (4), outside the hub and cutter, is

mounted the fork (8) carrying the pawl (9) with spring (10). At the end of the fork 20 (H) is hinged the handle (11). A stop (12) is provided to limit the motion of the fork beyond its vertical position, as shown in Fig. 3.

In using the machine to trim the edge of a 2 lawn, the cutter (l) is first pushed down into the soil, with the hub resting on the edge of the walk (13). The operators foot is then placed on the footboard (6) to steady it and to keep the cutter from rising up as it is 1927. Serial No. 193,284.

cutting the grass. By varying the position of the foot, either forward or back, the friction of the heel piece on the walk is controlled, so as to give the cutter more or less of a draw out through tough-cutting grass. Forward propulsion of the edger is performed by alternately pushing down and raising the handle (11), thus giving the cutter and roller an intermittent rotating motion.

As will be seen from Figs. 1 and 4, the cutter spindle (4) is set at an angle to the frame (5) in both the horizontal and vertical planes. This causes the forward part of the cutter to rub against the edge of the walk as it rotates, and so keeps it constantly sharpened.

I claim:

A lawn edge trimmer comprising in combination a foot board supported at one end by a shoe and at the. other end by a roller, a cutter secured to said roller, an operating handle, and cooperatingpawl and ratchet means operated by said handle for turning said roller to advance the implement along the edge of a walk, said cutter being mounted at an angle so as to rub against the walk, making it self-sluirpening.
